[0001] The utility model relates to the technical field of graphite material processing related equipment, in particular to a graphite feeding device. Background Art

[0002] Graphite powder is the most commonly used negative electrode material for lithium batteries. During the processing, the graphite powder needs to be fed into the filtering device through the feeding device for filtration, and then transported to the next processing equipment for processing, as shown below.

[0003] After searching, the patent with the authorization announcement number CN220563826U discloses a graphite negative electrode powder feeding device, including a feeding box and a purification box, a conveying auger is rotatably provided in the feeding box, a filter box is fixedly connected to the inner wall of the purification box, and the feeding box is communicated with the filter box through a discharge pipe, and a reciprocating screw is also rotatably connected to the inner wall of the purification box, a screw nut is threadedly connected to the reciprocating screw, and a knocking rod is fixedly connected to the lower end of the screw nut, and the end of the reciprocating screw away from the screw nut is fixedly connected to the rotating shaft of the conveying auger. The utility model is provided with a reciprocating screw, a screw nut and a knocking rod, which can drive the reciprocating screw to rotate continuously during the rotation of the conveying auger shaft, so that the screw nut and the knocking rod can be driven to move back and forth, thereby continuously knocking the filter surface of the filter box, which can promote the shedding of larger graphite powder particles, prevent them from affecting the passage of subsequent powder, and effectively improve the overall processing efficiency.

[0004] However, the above patent still has the following aspects that can be optimized:

[0005] First of all, although the method of using a knocking rod to move back and forth and knock on the filter box can prevent the mesh of the filter box from being clogged to a certain extent, in the process of the knocking rod constantly knocking on the filter box, not only will it continuously generate loud noise, but it will also easily damage the filter box due to continuous impact, causing unnecessary losses and waste, and reducing the service life of the entire device. Secondly, when it uses high-pressure air to further dredge the filter holes of the filter box, a large amount of graphite powder will be scattered in the interior of the purification box, and may be adsorbed and accumulated in various structural gaps inside the purification box, which will not only cause a large amount of powder waste, but also greatly increase the difficulty of regular cleaning inside the purification box. At the same time, it is difficult for high-pressure air to blow off the particles stuck in the filter holes, and the dredging effect is average. Therefore, its overall structure needs to be improved and its practicality needs to be improved. Utility Model Content
